The Arizona Diamondbacks blew a 6-0 lead in a loss in Cincinnati's Great American Ballpark today. The loss resulted in a split four-game series against the Reds. Despite hot strong start, the D-backs fell 6-7 in what could arguably be considered their worst loss this season.

The good news is the D-backs will now head back to Arizona for a 10-game home stand. Since May 23, the Diamondbacks have posted a 16-7 mark at Chase Field. They're still below .500 and seven games back in the NL West.

After a half-hour rain delay, Willie Bloomquist led off in the first with a single, stole second and scored on a Paul Goldschmidt hit. Goldschmidt stole second on a missed throw, but Chris Young's ground out ended the inning just one batter later.

The Reds went three up, three down in the first two against D-backs starting pitcher Joe Saunders, which allowed Arizona to widen their lead in the third off an Aaron Hill single that drove in a run.

In the fifth, Hill smashed his 13th homer this season, bringing the score to 3-0. Before today's start, Hill lead the D-Backs with 102 hits; he's on a 10-game hitting streak.

Chris Young and Justin Upton gave fans a taste of last season's golden days with back-to-back doubles in the sixth. Both players smacked them to deep left, with Upton scoring on Young's hit. Henry Blanco (catching on Miguel Montero's off day) homered, driving in two more and raising the total to six unanswered Arizona runs.

Then things got ugly.

The sixth inning gave the top of the Reds rotation a chance to rally - and they did. Drew Stubbs singled to center and Wilson Valdez singled immediately after. Brandon Phillips homered, bringing in all three runners.

In the bottom of the seventh, D-backs relief pitcher Bryan Shaw walked outfielder Xavier Paul (pinch hitting for Simon.) Shaw then walked Stubbs, allowing Paul to score on a crucial Goldschmidt error. Phillips then doubled to center, allowing both Stubbs and Valdez to score and tie the game.

With runners already in scoring position and the game in the balance, the D-backs substituted Mike Zagurski for Shaw. That lasted just one batter before Brad Zeigler got his chance on the mound. Pitching changes aside, Frazier singled to center, allowing Phillips to score what would become the deciding run.

Trailing by one in the eighth, the middle of the D-Backs order failed to get anything done. A 1-2-3 inning -- thanks to D-backs reliever Daniel Hernandez -- kept the score close, but in the ninth Hill fouled for an easy first out. Kubel and Goldschmidt both struck out swinging to seal the deal and give the Reds their biggest comeback in over five years.

The Diamondbacks will be back at Chase tomorrow to start a three-game series against the Huston Astros (34 - 58). Friday's starting pitcher Trevor Cahill suffered a 3-1 loss in his last start, allowing three runs on four hits and three walks in just over five innings. Right-handed pitcher Bud Norris will pitch for the Astros, who have lost 14 of their last 18 against the D-backs.
